What Are the Hidden Costs That Make a Patio Cost More Than the Quote?

You got a quote for a patio and built your budget around that. Then somewhere between the start of the job and when they put down that last paver, the price changed. Every patio job in Savannah has that potential concern, and it’s a legitimate worry because a patio quote is one of the easiest numbers in construction to look good to a consumer.

My name is Randy Thompson, founder of All Out Hardscapes & Lighting Solutions. Over more than 10 years we have built more than 150 patios, walkways, and outdoor living spaces across Savannah and the Coastal Lowcountry, from Wilmington Island to Savannah Quarters, and I am a Techo-Bloc Pro certified installer. I have written quotes that held true down to the dollar, and I’ve written a quote that changed by six grand because of something buried in a backyard that nobody knew was there.

Here’s what I’ve learned after doing this for over a decade. Almost every dollar that pops up as a hidden cost on a patio build comes from one of two things. Either something was left out of the quote on purpose so it was an easier sell, or there is something buried under the backyard that nobody knows about. The first issue is avoidable by just being truthful. The second thing is manageable, as long as your installer tells you about it before you sign anything, not spring it on you later.

Why Does the Final Number Land Above the Quote?

Because most quotes only give you a price on the part you can see, they leave out the part that holds it all up. A patio is a structure like a very small building. The pavers are only the top inch and a half of it. Everything that keeps that top layer flat and uncompromised for years is underneath, out of sight, and it’s way too easy for companies to leave that off of a quote.

There are five places the money hides on a patio job:

• The gravel base and the stone the pavers sit on
• The special joint filler sand that locks the pavers to each other
• The digging, the hauling off, and the labor
• Whatever is buried under the spot you picked
• Putting the lawn back how it was after the job is done

The first three things are choices. The last two are the conditions of your property. In our work across the Lowcountry, the quotes that change on you are only pricing the surface, not the whole thing. The quotes that you can actually count on are priced for the whole structure and say so in writing.

What Does a Per-Square-Foot Paver Price Actually Cover?

Most material pricing you find online is quoted the same way, and if you understand it, it’s not a trick or bait and switch. It’s just how the material is sold. It becomes a problem when someone sees a material price and assumes it’s a price for the whole patio.

The range people see is $6 to $18 per square foot, but that is strictly for the pavers themselves that are sitting on a pallet. That price doesn’t cover the gravel underneath or the bedding stone or the sand in the joints. The base and the bedding alone add about $8 per square foot before any labor or anything.

So here’s how people fall into an unintentional trap. Somebody with a 400 square foot backyard multiplies 400 by $6 (the cost of the cheapest paver), and gets $2,400. When they call us, that’s what they are expecting to pay for a whole patio. Then we walk the property and give them a real price that includes the labor and base and everything, and it feels like a bait and switch because they didn’t understand what materials and labor actually go into a finished patio. The pavers are just one ingredient, not the whole meal.

When you get a quote with a per-square-foot figure, what you need to know is what it doesn’t include. Base stone, bedding stone, joint sand, excavation, haul-off, and labor are the six things that aren’t included in that number you were given. Get a price for each one of those things before you compare two bids, or you are comparing apples to oranges.

What Happens to the Price When Somebody Cuts the Base?

We build on an open-graded base, that’s the only way we build. That means 4 inches of #57 stone, which is a washed angular gravel about the size of a nickel with the fine dust screened out of it, topped with 2 inches of #789 chip stone, a smaller washed stone that screeds flat and gives the pavers a nice bed to set on. We don’t use sand under the pavers at all because it does not last.

If we skipped the gravel and built on sand like most builders do, we could shave about $5,000 off what we charge on most of our jobs. Then if we leave out the polymeric sand, which is a joint filler with a binder mixed into it that hardens once it gets wet, and put plain mason sand in instead, we could knock off another $1,200 or more.

That’s at least $6,200 difference for the exact same square footage. That’s how a cheaper quote gets you a bigger patio. The money did not disappear, it just went to the part of the patio that you can see, but the base underneath will not last.

Here’s the part nobody really explains to you. In the yards we dig across Chatham and Effingham counties, we are digging through sand that sits on top of clay, and clay does not let water drain very fast. Sand and stone dust hold that water in place, but open-graded stone has the dust and fine dirt washed out of it, so the gaps between the stones are always open and water runs down through the base and out instead of sitting there damaging your patio. The angular edges of the rock we use lock against each other under weight instead of rolling around like sand grains do. That’s why the base is the last thing you want to cut corners on. You’ll be able to enjoy the patio for three to five years, but then you will start seeing the issues. After a heavy summer rain a corner has sunk an inch lower than the rest and the joint sand has washed into the grass, then weeds start popping up between all the pavers.

What Could Be Buried Under My Backyard?

We quoted a job that was supposed to run two weeks at about $26,000. It actually ended up costing $32,000, because there was a septic tank sitting in the middle of where the patio was supposed to go that nobody knew about. The whole thing had to come out before we could build anything on top of it. It was nobody’s fault, nobody knew it was even there.

Most of the time in a Savannah backyard we are going to hit something when we start digging. It could be an abandoned septic tank, a slab of old concrete under six inches down, an irrigation line nobody mapped, or tree roots as big as your arm. That’s why we add an extra week to the schedule before we even start. We always try to under-promise and over-deliver, so the surprise is just a conversation, not the entire project.

You can’t price for what is buried under the yard until you start digging, and any installer who tells you otherwise is only guessing. What you can do is be very clear about the process before you sign anything. Ask what happens when something is found, who makes the decision to keep going, and whether you see the updated price before or after the work is done. A change order you approved in advance is a cost, not a crisis. A change order you are surprised by on the final invoice can be.

Who Pays to Put the Lawn Back?

The patio is not the only part of the yard the job deals with. Every ton of stone, every pallet of pavers, and every bucket of dirt coming out has to cross your grass to get from the driveway to the backyard, more than a hundred trips over one week.

A machine with steel or rubber tracks, like a mini excavator or loader, turns by dragging one side against the ground. Every time it turns it scuffs turf or grass down to the dirt. Drive that across a lawn for a week and you’re going to need sod at the end of it. If the sod was not included in the quote, then you have to pay for that.

We pick equipment and drive it in a way that doesn’t tear everything up, so when we pull out you can look at the yard and see we have not disturbed the spots that weren’t part of the job. Before you sign anything, ask three questions. Ask what machine is coming, what path it takes to the backyard, and what condition the grass will be in the day we leave.

When Is the Cheaper Quote the Right Call?

Not every low number is low because it’s hiding something. Sometimes it’s lower because the job really is smaller, and the installer tells you that upfront. If one bid lists the base depth and the joint filler and the other one doesn’t, you aren’t getting two prices for the same job. You have one price for a patio and one price for just pavers on a pallet.

Some projects genuinely don’t need what we build. A small pad behind a shed for the trash cans, a landing at a side door, a basic walking surface that nobody really looks at and nobody entertains on, doesn’t need 6 inches of washed stone under it. If you’re listing the house in two years to sell and you want the backyard presentable rather than permanent, a less expensive build can be a better use for your money.

If what you want is a flat place to set two chairs and you are fine redoing it in five years, then there’s nothing wrong with buying exactly that. We just want you to know what you are buying, rather than find out in year three that you thought you were paying for something permanent, but got something temporary.

How Do I Get a Quote That Does Not Move?

We like being up front about it. What we hand you is an all-inclusive price for us to come out and perform the work, based on square footage, labor, and materials, in one number. We don’t give you a paver price with a separate install quote, and we don’t give you a per-foot price that doesn’t include the two things you need to hold your patio up. It wouldn’t be right to be dishonest about that number. We tell you what it really is so you have a price you can count on.

Whoever you end up hiring, these are the five things to make them put in writing:

• One price that includes square footage, labor, and materials, not a material price with a separate price for installation
• The base going underneath, listed with the depth in inches and stone size
• The joint filler going between the pavers, make sure they give you the exact product they will be using
• The process if they find something buried, including who approves the updated price
• The condition the lawn is left in, and who pays for sod if it is torn up

Any installer worth hiring can answer all five in one visit standing in your backyard. If those answers get vague, that’s a red flag.
